T0 LINE MATERIAL COMPANY OF SOUTH MILWAUKEE, WISCONSIN, A CORPORA- 'IIONOF DELAWARE SECONDARY RACK Application filed September 24, 1923. SerialNo. 664,474.

The invention relates to secondary racks.

The object of the invention is to provide a secondary rack, moreparticularly for use on line poles and other suitable supports, in whichthe usual malleable or steel brackets for carrying the insulatorsupporting rod are dispensed with and arms having direct connection withthe insulator supporting rod are bolted directly through and to the poleor support, thereby reducing the number of parts, the amount of materialand the cost of manufacture to a minimum.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the accompanying drawings, Fig. 1 is a side elevation of a secondaryrack embodying the invention, parts being broken away and parts beingshown in section, and

Fig. 2 is a transverse sectional View taken on the line 22 of Fig. 1.

In general, the device comprises supporting arms 20 each having a boltend portion, and a supporting rod or member 25- detachably connected tosaid arms and having insulators mounted thereon.

The bolt end portions of the supporting arms 20 are adapted to extendthrough a pole 9 or other support, and their ends are threaded toreceive nuts -21 by which the arms are clamped to the pole, an annularflange 22 being formed on an intermediate portion of each arm forengagement with one side of the pole. The insulator-supporting member 25is preferably a channel bar with its web provided with openings toreceive the threaded end portions 26 of the projecting arm 20, thechannel bar being clamped to these bars by nuts 27.

Spool insulators 29 are mounted on the member 25 against relativerotation, these insulators having polygonal holes therein through whichsaid member passes and being secured thereon against longitudinal displacement in any suitable manner, as by means of cotter pins 30 insertedin openings in the webs of the channel, washers 31 being preferablyprovided between the ends of each insulator and said pins 30. With thisabout one of the supporting arms on which it may be frictionally held bytemporarily tightening one of the nuts, thus permitting the use of bothhands while mounting new insulators.

It will be noted that the arms have bolt end portions and that the headsof these portions are arranged intermediate the ends of said arms tospace the insulator-supporting member at the desired distance from thesupport.

I desire it to be understood that this invention is not to be limited toany specific form or arrangement of parts except in so far as suchlimitations are specified in the claims.

IVhat I claim as my invention is 1. In a secondary rack, the combinationof a pair of spaced parallel bolts to fixedly enter a support andproject therefrom and each having an intermediate shouldered portionengageable with said support, and a straight channel rod secured to theprojecting end portions of said bolts to extend between said bolts inspaced relation to said support and having spaced spool insulatorsthreaded thereon.

2. In a secondary rack, the combination of a pair of spaced parallelbolts to fixedly enter a support and project therefrom, a channel rodhaving the opposite end portions of its web secured to the projectingportions of said bolts to dispose said rod between said bolts in spacedrelation to said support, and spool insulators threaded on said channelrod and fitting thereon against relative rotation.

In testimony whereof I affix my signature.

WILLIAM D. KYLE.
